Skate with improved steering capabilities

ABSTRACT

A skate having a support for the sole of an item footwear and for at least three aligned wheels, which has improved turning. The peculiarity of the skate consists of the fact that two wheels are arranged and rotate on a plane which is parallel to the plane of the remaining wheels. It is thus possible to obtain a right skate and a left skate with offset wheels which allow the user to achieve better turning.

BACKGROUND OF THE INVENTION

The present invention relates to a skate with improved steering capabilities.

Skates having aligned wheels are currently known, and they are ever more specifically used for speed skating and slalom.

The problem observed in these known types of skates, in which the wheels are pivoted at adapted supports which are rigidly associated with a supporting plate for the sole of an item of footwear, consists in the difficulty in achieving very tight turning radiuses.

Devices are known which allow to vary the distance of the axis of the wheels with respect to the ground, in order to adapt the skate to slalom or speed.

However, said devices are not practical to use and are expensive.

DE-G-9107661.7, for example, discloses such a skate with steering wheels.

SUMMARY OF THE INVENTION

The aim of the present invention is therefore to eliminate the problems described above in known types by providing a skate with aligned wheels by which it is possible to achieve a very tight turning radius.

Within the scope of the above aim, an important object is to provide a skate wherein turning can be achieved in a practical and easy manner for the athlete, requiring very little effort.

Another important object is to provide a skate which allows to achieve a turning radius which is as much as possible continuous, by means of devices having an extremely low cost.

Another important object is to provide a skate which is structurally simple and can be obtained with known machines and facilities.

Not least object is to provide an invention which associates with the preceding characteristics those of having low costs and of being at the same time reliable and safe in use.

This aim, the objects mentioned and others which will become apparent hereinafter are achieved by a skate with improved steering capabilities, comprising a support for the sole of an item of footwear and for at least three aligned wheels, characterized in that at least one of said wheels, which is arranged approximately in the median region, is arranged and rotates on a plane which is parallel to the plane of the remaining wheels.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the above FIGURES, a skate structure composed of a right skate and of a left skate, generally designated by the reference numerals 1a and 1b, will be considered specifically.

Each of the skates is constituted by an item of footwear, designated by the reference numerals 2a and 2b. A plate, designated by the reference numerals 3a and 3b, is associated at the sole of the item of footwear. A support, designated by the reference numerals 4a and 4b, and constituted by a pair of parallel wings, protrudes from the plate. Four aligned wheels are pivoted, between the wings. The wheels are designated by the reference numerals 5a, 5b, 6a, 6b, 7a, 7b, 8a and 8b respectively starting from the tip of the item of footwear toward the heel thereof.

The number of aligned wheels can range from a minimum of three upward. In the present case, an embodiment with four aligned wheels is described.

At each skate 1a and 1b, the wheels 5a, 5b adjacent to the tip of the item of footwear and the wheels 8a, 8b adjacent to the heel thereof are arranged and rotate at a same first plane designated by the numerals 9a and 9b.

Said first plane is advantageously arranged parallel to the median plane which is longitudinal to the supports 4a and 4b, preferably directed toward the outer lateral edge 10a and 10b of the items of footwear 2a and 2b.

The remaining wheels 6a, 6b and 7a, 7b, which are located centrally with respect to the supports 4a, 4b, are also arranged and rotate in a same second plane, designated by the numerals 11a and 11b, which is parallel to the first plane 9a, 9b.

In particular, said second plane 11a, 11b is arranged adjacent to the inner lateral edge 12a, 12b of the item of footwear 2a, 2b.

The arrangement of the various wheels can be achieved by interposing adapted spacers, designated by the reference numerals 13 and 14, on the axes of said wheels.

The arrangement of the wheels is such that, as illustrated in FIG. 4, during skating along a straight axis all of said wheels interact with the ground 15.

The operation of the skate structure is thus as follows: when following a straight path, all the wheels interact directly with the ground, ensuring excellent directionality to the skate.

If a turn is made, for example to the right as shown in FIG. 2, the left skate 1b interacts with the ground 15 only at the wheels 6b and 7b which, by being located in the median region of the support 4b, allow the user to achieve better control of the turning action, by having a very small center distance; the right skate 1a performs the function of increasing or maintaining the initial speed.

A similar situation occurs for the right skate 1a and the left skate 1b in a left turn.

It is also noted that along straight paths the user can enjoy a better support, since the wheels, despite being aligned, are arranged on mutually parallel planes, thus increasing stability during motion.

It has thus been observed that the invention has achieved the intended aim and objects, a skate having been provided which allows to achieve better turning as well as excellent support during straight-line skating.

The skate according to the invention is susceptible to numerous modifications and variations, all of which are within the scope of the same inventive concept.

Thus, for example, if there are three aligned wheels, the central one is axially offset with respect to the one located in the regions adjacent to the tip and heel of the item of footwear.

Similarly, if there are more than four aligned wheels, at least one of them, arranged approximately in the median region or in a region directly adjacent thereto, is arranged and rotates on a plane which is parallel to another plane on which one or more of the remaining wheels are arranged.

The materials and the dimensions which constitute the individual components of the skate may naturally also be the most pertinent according to the specific requirements.
